What should I do if the new buds of the wealth tree wither?
As a much-loved indoor leaf-viewing plant, the wilting of new buds of Fortune Tree is a common problem that plagues many flower lovers. The abnormal state of new shoots not only affects the appearance of the plant, but may also indicate hidden dangers in the maintenance process. This article will systematically analyze the six major maintenance points to help you quickly locate the root cause of the problem and revitalize the rich tree. 1. Scientific water management 1.1 Water shortage causes new buds to wither. When the soil water content is less than 40%, the plant's roots cannot absorb water normally. It is recommended to use a moisture detector for regular monitoring to keep the soil moist but no water accumulation. In spring and autumn, it is recommended to slowly water the edge of the basin with a long-spout pot every 3 days. In summer, it can be combined with leaf spray in the morning and evening. 1.2 Correct water replenishment techniques Use the "dipping basin method" to ensure that deep soil absorbs water: Place the flower pot in a water container and soak it for 15 minutes, and take it out and drain it after the surface soil is moist. Note that the water temperature in winter should be consistent with room temperature to avoid cold water stimulating the roots. 2. Precision fertilization plan 2.1 Remediation measures for fertilizer damage When the edges of new leaves are found to be scorched, fertilization should be stopped immediately. Use the "triple leaching method" to dilute the fertilizer: rinse it with clean water of 3 times the volume of the pot soil for 3 consecutive days, with an interval of 12 hours each time. In severe cases, the surface layer of 5cm soil can be replaced and 30% perlite can be mixed to improve air permeability. 2.2 Scientific fertilization cycle During the growth period (April to September), apply a 1:1000 dilution special liquid fertilizer for leaf-viewing plants every 15 days, combined with iron chelated foliar fertilizer once a month. Stop fertilizing during winter dormancy to avoid root burns. 3. Optimization of the Lighting Environment 3.1 Analysis of Lighting Requirements Fortune trees need to scatter light for 4-6 hours a day. Direct strong light will cause burns to the leaves. It is recommended to place it 1.5 meters away from the east-facing or north-facing sill and use a gauze curtain with a light-blocking rate of 30% to adjust the light intensity. 3.2 When the light filling system is built in winter, when there is insufficient light, a 10W full-spectrum plant fill light can be installed. The light is filled for 4 hours a day, and the lamp distance is maintained at 50cm. Match it with a 360-degree rotating flower stand to ensure that the leaves receive uniform light. 4. Regulation of environmental parameters 4.1 Humidity maintenance plan maintains the air humidity of 60%-70%. An ultrasonic humidifier can be configured, or the "double tray method" can be used: the bottom tray is paved with ceramite and water is poured, and the upper tray is placed with flowerpots with inverted trays. Pay attention to regular windows for ventilation to prevent the growth of mold. 4.2 Temperature management points to maintain the optimal growth temperature of 18-28℃, and heat preservation measures need to be taken when it is below 10℃ in winter. It is recommended to use a plant insulation cover to maintain the temperature at night and remove it during the day to ensure ventilation. 5. Pest and insect pest control system 5.1 Treatment of common pests For red spiders, you can spray the leaves with a 1:200 diluted Melia oil solution on the back of the leaves for 3 consecutive days. It is recommended to use a cotton swab dipped in 75% alcohol to kill scale insects, and use it to hang a yellow sticky board for physical control. 5.2 Disease prevention strategy Apply Bacillus subtilis biological agents once a month to enhance plant disease resistance. When leaf spot disease was found, the affected leaves were cut off immediately, 800 times mancozeb solution was sprayed, and the application was repeated at 7 days intervals. 6. Nutrient element management Regularly detect soil EC values and maintain them within the range of 1.2-1.8mS/cm. When new leaves turn yellow when nitrogen is deficient, calcium nitrate can be applied topologically; when old leaves are deficient in potassium, potassium sulfate should be added to the charred edges. It is recommended to use seaweed extract once a quarter to promote the absorption of trace elements.
Through systematic maintenance and management, new shoots can usually be observed to resume growth in 2-3 weeks. The key is to establish an observation log, record data such as watering, fertilization, and environmental parameters, and gradually grasp the rules of plant growth. When new shoots germinate again, brassinolide can be appropriately supplemented to promote strong growth.
